The BTH KD1 Competition magneto was the standard fitment to competition Norton Internationals and SOHC Manx Nortons. The competition versions (identified by a brass plate on its side reading either 'TT Magneto' or 'Dirt Track Magneto' and having the icompetition designate in its serial number) were fitted with platinum points and a manual advance/retard mechanism with a 3 screw inspection cover. I can supply most parts to fit this magneto and also occasionaly I have second hand parts as well. PLEASE NOTE: Some of the prices quoted in this section - particularly for small stainless steel screws may seem expensive compared to other commercially available nuts and bolts. Please bear in mind that this is because they are being made specially in small batch's for this magneto. Unfortunately the machinist charges for the number of machining operations - not the size of the screw!!

- Copper shims that fit behind the manual advance unit, used to adjust correct end float when fitting new bearings
- As a rule of thumb, I normally expect 2-3 of these to be fitted (sometimes more), dependent on bearing fitted. E-mail me if you require advice around end float etc.
- 15/08/11: Unfortunately I am out of stock of these items and my supplier is not looking to have them again in the near future. If you do require them please let me know and I will consider having a pattern for the shims made

- Graphite HT Pick Up ferrules with spring attached (these are frequently worn on used magnetos) - I find that if this needs replacing, it also benefits to clean the slip ring contact. Great care should be taken when doing this not to damage the slip ring

- High quality 'Standard' type (i.e. not platinum) BTH KD1 Contact Breaker Points Set, from trusted UK supplier. Sorry these are not cheap, but are the proper thing and good quality (some others you may see advertised may be cheaper alternatives that do not work as well).
Note: I can also obtain by special order the original competition type platinum points, however, these are extremely expensive. Please email me for details

- Proper Competion PLATINUM BTH KD1 Contact Breaker Points Set These are the correct platinum contact breakers, as were originally fitted to genuine competition KD1 magnetos, and the key differentiatior between the racing version and the standard version. Sorry they are so expensive, but I dont control that - I am saving myself so I can use a set on my next KD1 rebuild!

- Stainless steel hex head tapered screws for competition BTH housings. Drilled to take lockwire, just as the originals were. Sorry they are not cheap, but they do look the business when fitted, particularly with the lockwire!
Note: only 3 required per magneto

- This is the large width housing plug that fits into the bottom of the KD1 manual advance/retard housing, at the base of the cable mechanism, often missing (fitting it helps prevent corrosion and dirt entering the mechanism). Dull nickel plated as per original

- Stainless Steel safety gap screws.
Sorry - I no longer stock this part. Actually I am not sure why I ever did, because actually it is not fitted to a KD1 magneto, it is meant for the BTH twin magneto. If you do need one, let me know and I will see if I can get one for you by special order

- I have found NGK the best and most reliable spark plugs caps you can get , and have been using this type on my road bikes for the last 20 years - they are without doubt the best value for money spark plug cap available and include waterproofing covers.

- NGK modern LB05EMH competition spark plug caps with resistor to protect against RFI interference - Waterproof and probably the best cap you can use if you are using the bike seriously - but not cheap! - I also include the small nylon tie band that NGK have stopped supplying themselves now!

- This woven cloth HT lead is of the type originally used on competition BTH magnetos in the 1930's and 1940's, and looks great for the authentic finishing touch on your comeptition bike restoration. Price is per foot.
- I use this on my rigid and plunger framed Nortons
- Note: Recently a customer informed me that the HT lead got soaked in the rain, and the spark was lost, as it shorted across the cloth. Please can I suggest that if you use the bike in all weathers, you may want to cut back the cloth 10mm on each end where it feeds into the Pickups, to minimise this.

- I have finally been able to find a batch of the correct type of PVC yellow and black competition HT lead, as used on almost every type of competition magneto from the 1950's onwards (recently this type of cable has been very difficult to obtain). Price is per foot.

These are the split brass washers that are soldered to the end of the HT lead that is screwed into Lucas and other similar magnetos that use screw in HT connections. Using these washers give a good connection and retains the HT lead as the was. Price is for pack of 4
